Lyons, in Working Guide to Reservoir Engineering, 2010 Resistivity Tools The purpose of resistivity tools is to determine the electrical resistance of the formation (rock and fluid). Since most formation waters contain dissolved salts, they generally have low resistivities.
WebJul 28, 2016 · Interval transit time (∆t), measured in microseconds per meter [foot] and often referred to as slowness, is the reciprocal of velocity. Lithology and porosity affect ∆t. Dense, consolidated formations characterized by compaction at depth generally result in a faster (shorter) ∆t while fluid-filled porosity results in a slower (longer) ∆t.
